Leaf waxes in Coincya Rouy (Brassicaceae)
Botanical Journal of the Linnean Society, 1994Abstract A total of 55 populations belonging to the genus Coincya Rouy (Brassicaceae) from the Iberian Peninsula were examined for their leaf wax composition. The total wax content and the relative proportions of the five main lipid fraction, hydrocarbons, esters, ketones, free alcohols and free sterols were determined.

The external surface of the higher plants comprises a cuticular layer covered by a waxy deposit. This deposit is believed to play a major part in such phenomena as the water balance of plants and the behavior of agricultural sprays. The wax contains a wide range of organic compounds.

Abstract Leaf waxes from spring wheat varieties Selkirk and Manitou contain hydrocarbons (6%, 10%), long chain esters (14%, 13%), free acids (5%, 8%), free alcohols (19%, 21%), β-diketone (16%, 20%), hydroxy β-diketones (8%, 10%), unidentified gum (29%, 16.5%) and minor amounts of diol diesters, glycerides and aldehydes.

Solubility of parathion in orange leaf wax
Bulletin of Environmental Contamination and Toxicology, 1977The solubility of parathion in orange leaf wax at 25°C is therefore 0.5 g/g of wax, which is equivalent to approximately a 30% solution. This high solubility and previously demonstrated in-wax-solution stability clearly demonstrate that citrus leaf waxes may be an important factor in citrus picker “reentry safety.”

Plant Science Letters, 1976
Abstract The effect of environmental conditions on the chemistry and morphology of Clarkia elegans leaf wax has been examined using gas liquid chromatography and scanning electron microscopy. Chemically the wax consists of a mixture of hydrocarbons, ketones, alkyl esters, aldehydes, primary alcohols and secondary alcohols of which nonacosane ...

Secondary alcohols from Fragaria leaf waxes
Phytochemistry, 1979Abstract The secondary alcohols isolated from Fragaria leaf waxes and characterised by GC-MS have been shown to be a mixture of isomers of hentriacontanol with the hydroxy substituent on carbons 9, 10, 11 and 12, and of tritriacontanol with the OH group in the 10, 11, 12, 13 and 14 positions, respectively.

Leaf wax ketones in the genus Coincya
Phytochemistry, 1996Abstract Leaf wax ketones in the genus Coincya vary between C 22 and C 31 , and is dominated by those with an odd number of carbon atoms. The most abundant ketones are C 25 , C 27 and C 29 . The main one, C 29 , ranges from 57.7% in C. monensis subsp. cheiranthos var. setigera to 21.2% in C. monensis subsp. nevadensis .

Interspecific variation in leaf wax of Dudleya
Biochemical Systematics and Ecology, 1979Abstract The distribution of the pentacylic triterpenoids, β-amyrin acetate and taraxerone, in the glaucous epicuticular wax of Dudleya subgenus Dudleya is correlated with both the geographic distribution and corolla tube length of a particular species. This is significant in a genus with many systematic problems.

Leaf wax alkanes in the genus coincya
Phytochemistry, 1994Abstract Leaf wax alkanes in the genus Coincya vary between C 22 and C 31 . This series is dominated by alkanes with an odd number of carbon atoms. The most abundant alkanes are C 29 , C 31 and C 27 . The main one, C 29 , ranges from 53.3% in C. monensis subsp. nevadensis to 95.0% in C. monensis subsp. recurvata var. setigera .

Leaf wax constituents of some myrtaceous species
Phytochemistry, 1983Abstract Eucalyptin and 8-desmethyleucalyptin have been isolated from the leaf wax coatings of several species of Eucalyptus, from Syncarpia glomulifera, Lophostemon confertus and an Angophora hybrid indicating that C-methylated flavones may be fairly distinctive of the family Myrtaceae.
